PUMP.

To all whom it may concern:

Be it known that I, MARTIN Nnss, a subject of the King of Norway, residing at Bothell, in the county of King and State of Washington, have invented certain new and useful Improvements in Pumps, of which the following is a specification. I

My invention relates to that class of pumps which utilize compressed air to act directly upon a bodyof water to expel the 7 same from a pumping chamber.

The object of the invention is the improvement in pumps of this character; and it consists in the novel construction and combination of devices as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view of a pump embodying my improvements. Fig. 2 is a similar view with the valves and controlling devices therefor shown in difierent positions than in which they are represented in Fig. 1. Fig. 3 is a perspective view of-the airvalve and the operating arm therefor.

The reference numeral 5 designates a pumping-vessel provided at its lower end with a communicating1 cylindrical chamber 6. Extending throug said vessel and for 6 is liquid discharge pipe 7 having at its lower end an automatically acting non-return valve 8. sprin closed one-way valve 9 admits liquid amber 6 through an opening 10 pro- Connected to the upper end of the pumping vessel are pipes 11 and 12 through which compressed air is respectively supplied to and discharged from the pumping-vessel. The pipe ll may be connected with an air-pump or reservoir wherefrom air under pressure is supplied to serve as the power agent whereby the pumping operation is eifected. 13 represents a casing for a three-way valve 14, said casing being provided with two passages 11 and 12 which connect the air pipes with the bore of the valve casing. The valve 14 is formed hollow and is open at one end to'hav'e the interior cavity of the valve in continuous communication .with the interior of the pumping-vessel.

In the periphery of valve 14 is a port I? which is disposed to register with the passages 11 and 12 when the valve is suitably rocked. Fixedlv secured to valve 14 is an arm 15 having its free end forked, and depending from the latter at-diametrically op- Specification of Letters Patent.

7 are rods, such as i thereto by posts 19 is an annular plate 20 of an external diameter slightly less than the internal diameter of the chamber 6. The opening 20 of said plate is made of a size to accommodate pipe 7 and the rods 16 to permit the plate moving unrestrainedly up and down with the float. v

21 is a helical spring surrounding pipe 7 and supported by the float.

To operate submerged in water. When the various operating parts occupy the positions in which they are illustrated in Fig. 1, the pressure due to the head of water surrounding the pump will cause the Water to flow into the vessel through openin 10 and chamber 6 oat 18 while the air escapes through pipe 12. As the float a proaches theupper'end of the vessel, t e spring 21 is brought against the forked end of the arm. 15 to first compress the spring and to eventually influence the arm to act the valve 14; td be rotated into the position in which it is shown in Fig. 2, resulting in the closing ofthe air exhaust passage 12 and the opening Whereupon, air under pressure will enter the vessel and exerts a downward pressure upon the previously admitted body of water to drive the same through the delivery pipe 7 As the the plate 20 encounters the ring 17 and carries it therewith to exert a doivlrnward pull upon the rods 16 to grad- -ua y swing valve 14 into closedv osition with respect to air exhaust passage 12 W e the plate 20., however, en rs the chamber 6 the momentum of the water in its flow to the water delivery pipe drags the plate downwardly with'consi erable seed and in opposition to the buoyancy o the float toimpart a qluick opening movement of the valve 14 wit regard to the air outlet passage 12, to allow the air to be quickly exhausted by the replacement of water.

What I. claim, is-

1; In apparatus of the class described, the combination of a pumping-vessel provided with air inlet and outlet openings, a threeway valve for controlling said openin s, an arm connected to said valveJoL cylin rical the invention the vessel 5 is inlet, a spring closing valve for the water inlet, a water discharge pipe extending through said vessel and into said chamber,

a non-return valve for said'pipe, a float, an element surrounding said pipe and posii tioned below said float and operatively connected with said arm whereby .the latter is influenced by the float in its downward movements to open the three-way valve with respect to the air outlet, and a plate secured to said float and operable within said chamber for regulating the motion of the float and the three-way valve during the referred to opening of the same.

2. In apparatus of the class-described, the combination of a pumping-vessel provided with air inlet and outlet openings, a threeway valve for controlling said openings, an arm connected to, said valve, a chambercommunicating with the lower end of said vessel and provided with a water inlet, a valve for the water inlet, a water discharge pipe extending through said vessel and into said chamber, a non-return valve for said pipe, a float, an element positioned below said float and operatively connected with said arm whereby the latter is influenced by the float in its downward movements to open the three-way valve with respect to the air outlet, said float also serving ,in its upward movements to open the three-way valve for the admission of air from said outlet opening, and a spring carried by the float and engageable with said arm in the upward movements of the float for influencing the opening of the three-way valve with respect to the air inlet.

3. In apparatus of'the class described, the combination of apumping-vessel provided with air inlet and outlet openings, a' threeway valve for controlling said openings, an arm connected to said valve, a cylindrical chamber communicating with the lower end of said vessel and provided with a water inlet, a spring closing valve for the water inlet, a water discharge pipe extending through said vessel and into-said chamber, a non-return valve for said pipe, a float, an element surrounding said pipe and positioned below said float and operatively con-. nected with said arm whereby the latter is influenced by the float in its downward movements to open the three-way valve with respect to the air outlet, a plate secured to said float and operable within said chamber for regulating the motion of the float and the three-way 'valve during the referred to opening of the same, and a spring carried by the float and engageable with said arm in the upward movements of the float for influencing the. opening of the three-way valve with respect to the air inlet.

4. In apparatus of the classdescribed, a pumping vessel provided with air inlet and outlet openings, a single valve for alternately opening and closing said openings,

an arm connected to said valve, a float, a,

spring carried by-the float, and an element suspended from said arm, said spring and element being adapted to be successively actuated. by the ,float in the upward and downward movements of the latter thereby influencing said-valve to permit the passage of air through the respective openings.

5. In apparatus of the class described, the combination of a pumping-vessel having a water inlet and provided with air inlet and outlet openings, a three-way valve for controlling said openings, an arm connected to said valve, a chamber communicating with the lower end of said vessel and provided with a water inlet, a valve for said water inlet, a pipe for the discharge of water from the lower end of said vessel, a non-return valve for said pipe, a float, and an element positioned below said float and operatively connected with said arm whereby the latter is influenced by the float in its downward movements to open'the three-way valve with re-, spect to the air outlet, said float also serving in its upward movements to open the threeway valve for the admission of air from said outlet opening.
